In Figs. 1 and 2 we have shown the strip 7 provided with aninner reinforcing-strip 23. Thisinner strip is formed of material whichwill rapidly expand when subjected to heat, thus insuring the lateralmovement of the strip 7 when the gas is ignited.

In the foregoing description we have shown the preferred form of ourinvention; but we do not limit ourselves thereto, as we are aware thatchanges may be made in the form, proportion, and minor details ofconstruction without departing from the spirit or sacrificing any of theadvantages of the invention, and we therefore reserve the right to makesuch changes as fall within the scope of our invention.

Having thus described the invention, what is claimed as new is 1. Thecombination with a burner having a slide-valve therein, of a thermostatextending over the burner and connected to the valve, an arm extendingfrom the thermostat, and a valve-opening lever connected to the burnerand separate from but adapted to engage the arm to lock the valve inopened position.

2. The combination with a gas-burner having a slide-valve therein, of aslotted thermostat secured to the burner and extending thereover, saidthermostat engaging the valve, a hooked arm extending from thethermostat, a springcontrolled lever connected to the burner, and a hookupon the lever for engaging the arm.

3. A burner comprising a tube having a tip on one end thereof, a plugwithin the tube having a passage therethrough, a slide-valve within theplug and tube and normally closing the passage, a longitudinally-slottedbowed thermostat secured to the tube and extending over the tip, saidthermostat having a slotted end adjustably connected to the valve, aring secured to the thermostat and loosely inclosing the tube, and apivoted lever connected to the tube and adapted to operate thethermostat to open the valve.

4. A burner comprising a tube having a tip on one end thereof, a plugwithin the tube having a passage therethrough, a s1 ide-valve within theplug and tube and normally closing the passage, a longitudinally-slottedbowed thermostat secured to the tube and extending over the tip, saidthermostat having a slotted end adjustably connected to the valve, ahooked arm, extending from the thermostat, and a spring-controlledhooked lever mounted upon the tube and adapted to operate and engage thearm.

5. A burner comprising a tube having a tip on one end thereof, a plugwithin the tube hav ing a passage therethrough, a slide-valve within theplug and tube and normally closing the passage, a longitudinally-slottedbowed thermostat secured to the tube and extending over the tip, saidthermostat having a slotted end adjustably connected to the valve, ahooked arm extending from the thermostat, a loop inclosing and pivotedupon the tube, a hooked arm extending therefrom and adapted to bear uponand operate the arm of the thermostat, a spring connected to the loop,and an oper ating device depending from the loop.

6. A burner comprising a tube having a tip on one end thereof, a plugwithin the tube having a passage therethrough, a slide-val ve within theplug and tube and normally closing the passage, a longitudinally-slottedbowed thermostat secured to the tube and extending over the tip, saidthermostat having a slotted end adjustably connected to the valve, aring connected to the thermostat and loosely inclosing the burner, andmeans for operating the thermostat to open the valve.

7. A burner comprising a tube having a tip on one end thereof, a plugwithin the tube having a passage therethrough, a slide-valve within theplug and tube and normally closing the passage, a longitudinally-slottedbowed thermostat secured to the tube and extending over the tip, saidthermostat having a slotted end adjustably connected to the valve, aring secured to the thermostat and loosely inclosing the tube, a collarsecured to the tube, a hooked arm thereon, a loop pivoted upon saidcollar and inclosing the tube, a hooked arm thereon, a hooked arm uponthe thermostat adapted to be engaged thereby, a spring connected atopposite ends to the loop and the arm of the collar, and an operatingdevice connected to the loop.

In testimony whereof we ailix our signatures in presence of twowitnesses.
